CAR HEATER.

i `Application led January 2.2, 1926. Serial No. 83,083.

This invention relates to a heater, particularly designed for the well-known I-Iudson car. The principal objects of the invention are to provide a heater for receiving thev fresh air as it is drawnv throughV the radiator by the fan and thc forward motion of the car, passing the air over the exhaust manifold in such a way as to heat the car efliciently and retain the heat in the air until it can bedistributed inthe car; also to provide a conductor constituting anecesusary part of the heater` located at the top of the exhaust pipe elbow so that the air will b e heated further/'at this point.

Other objects of the invention are to form the heater in three-parts of cast iron to add to the eiiiciency by retaining the heat in the cast iron walls, and to provide a heater which can be applied to a Hudson car without cutting or altering any part of the car except the rubber floor mat. Incidentally by causing the air current tol be. carried along the surface of the manifold, a little added to the cooling effecton the engine. ze The invention is also designed to provide for a very simple and inexpensive construction and especiallya very simple way of mounting it on the engine. Other objects and advantages of the invention will appear hereihafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a side view of a heater constructed in accordance with this invention and applied to a Hudson car;

Fig. 2 is a plan of the same; Fig. 3 is a view of the register taken in y the direction of the arrowA 3 in Fig. 1';

iii)

Fig. 4 is a sectional view of the sameon the line 4- 4 of Fig. 3, and

Fig. 5 is a sectional view of the stove on the line 5-.5 of Fig. 2 showing the outline of the exhaust manifold in elevation.

"In the application of this 'invent-ion advantage is taken fof the fact that the air circulated by the fan, and also `the outer air current due to the motion of the car, passes backwardly along the exhaust manifold of the engine. In order to take advantage of this current of air, we conne it and deliver it. at the desired point for heating the interior of the car. We employ as a lstove for the heater, a casting 10 w ich is provided with two clips 11 and 12, pivoted toits front edge, which is vertical, and

.also of cast iron,

424 in the plate 20.

`bolted rigidly to the Wall of the manifold.

These are sufficient to hold ,the stove in position, but we provide a strap 13 bolted to the top of the engine, bent down so as to .engage the top of the inner edge of the stove. near 60 the engine. to keep the stove from vibrating at that point. This simply holds down the inner edge of the stove;

The stove itself consists of a casting las stated which has a fiat top and vertical' side 65 walls.' There is no bottom or rear wall excepta, short wall 14. The edges of the vertical wall rest on the manifld and seal the stove at that point. -The air enters through an inlet opening 15 provided in a reduced 70 portion of the casting and directly 4open to the air currentsas indicated in the drawings. 'The air necessarily passes along in the stove casting, beingconcentrated therein and held so that 'it comes in contact with 75 the manifold and is heated materially in its course through the stove.

At the outlet end the stove is provided with an openingbetween the 'wall 14 andthe opposite front Wall into Which projects the end 16 of a pipe 17, which is also formed as a casting, but has all four walls so as to conduct the heated air from the stove to the y car. This casting does not have to be fas-"1 tened to the' stove but its discharge end is 85 made to t in the right hand drive hole in the toe board of the car.. At that end it en-y ters the-car far enough tosteady it there. The casting 17 is located so as to rest on the top .of the exhaust pipe elbow with which the 9c en ine is provided. A

- s the pipe'passes into the car through the drive hole and through a hole made in the rubber mat, it is provided with a plate 20,

' secured to the pipe by 91 screws 30. This plate is held against the rubber which it squeezes atits edges and it lcloses the op'en end of the pipe 17. It is provided with a discharge opening 21 which is adapted to be closed by an adjustable slide 1 22 having a knob 23'passing through a slot The knob has a spring 25 to hold the plate 22 in any desired adjusted position. Thus the register may be opened or closed or left in an intermediate 1 position as may be desired. v f

' It will be seen that, by making this hea-ter in threeparts of cast iron, the air is protec-ted from theproducts of combustion and and `described but what we do claim is:

active currents which insure its distribution in the can Also it will be suliciently heated during its passage from one endof the engine tothe other. f The stove is secured in place in the simplest possible manner and can be removed' readily ifnecessary.' It occupies no extraspace likely to be used for other things or ordinary repairs and has no projection on jthe inside of theear that would be. in they Way.4 It is capable of ln'e regula tion.

v Although 'We have illustrated and described only a single form of the invention -l and shown it is designed for a Hudson car,

We are aware of the fact that modifications can be made therein by any person skilled in the art without departing from the -scope of the invention as expressed in the claim.

Therefore, we do not Wish to belimited to all the details of construction herein shown V 1,658,966, Y v
